嗨rockthaworld123，



关于这一点，我需要从你这边做一件事。用户按下注销选项时需要后退按钮功能。如果你不需要手段只是你可以禁用后退按钮设施，但它是浏览器的可靠性。通过使用以下代码，您可以在应用程序中禁用后退按钮功能





window.history.forward（）;

函数noBack（）{window.history.forward（）; }







onpageshow =if（event.persisted）noBack（）; onunload =>



您需要后退按钮功能，只需在用户按下应用程序中的按钮时重定向主页



可能会对你有所帮助





谢谢和问候，

Hi rockthaworld123,

One thing i need from u r side regarding of this. you need back button pressing facility while user pressing logout option. if u dont need means simply u can disable back button facility , but it is browser dependability. By using following code you can disable back button press feature in your application


window.history.forward();
function noBack() { window.history.forward(); }



onpageshow="if (event.persisted) noBack();" onunload="">

and you need backbutton facility means simply redirect home page when the user press back button in your application

Might be it will help to you


Thanks and Regards,

另一种解决方案是，在所有页面中不使用缓存。它强制浏览器重新加载user.apsx而不是从缓存中读取。

首先，在标题中使用这些代码：

Another solution is, use no cache in all of your pages. It forces the browser to reload user.apsx instead of reading from cache.
First, use these code in your header:

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache">

其次，你必须确保你的user.aspx不允许在没有有效会话的情况下直接打开。

Secondly, you must ensure that your user.aspx doesn't allow to open directly without a valid session.

试试这个,,,, :)

Try this,,,,:)

Session.Clear();//clear session
Session.Abandon();//Abandon session
Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();
Response.Redirect("yourUrl.aspx");
